Abstract: A cloaking device assembly comprises an object-side, an image-side, a reference optical axis extending from the object-side to the image-side, a cloaked region positioned between the object-side and the image-side and a cloaked article positioned within the cloaked region. An object-side converging lens is positioned on the object-side, an image-side converging lens is positioned on the image-side, and a hexagonal prism is positioned within the cloaked region between the object-side converging lens and the image-side converging lens. Light from an object positioned on the object-side of the cloaking device and obscured by the cloaked region propagates through the object-side converging lens, the hexagonal prism, and the image-side converging lens to form an image of the object on the image-side of the cloaking device such that the cloaked region and the cloaked article within the cloaked region do not appear to be positioned between the object and the image.

Abstract: A cloaking device comprises an object-side, an image-side, a cloaked region between the object-side and the image-side. An object-side optical component and an object-side tilt correction (TC) component are positioned on the object-side, and an image-side optical component and an image-side TC component are positioned on the image-side. The cloaking device is tilted relative to an object positioned on the object-side such that light from the object is incident on the cloaking device at an acute angle. The object-side TC component redirects light from the object incident on the cloaking device such that the light propagates through the cloaking device generally normal to the object-side and image-side optical components. The image-side TC component redirects light propagating through the cloaking device back to normal to the object to form an image of the object on the image-side of the cloaking device which, if not for the TC components, would be distorted.
